Thick or Thin Ice Shell on Europa?
http://photojournal.jpl.nasa.gov/catalog/PIA10131 Europa Tide Movie http://photojournal.jpl.nasa.gov/catalog/PIA10149 I'm not sure that there is any new science involved. Seems to me like some nice eye candy for the purpose of getting Europa into the collective consciousness before the next flagship is chosen. |

Incidentally, I think on the first one, they got the apparent motion of Jupiter completely backwards while moreover depicting Jupiter as tidally locked WRT the Sun (or somehow otherwise rotating other than the way it actually does).

Incidentally, I think on the first one, they got the apparent motion of Jupiter completely backwards while moreover depicting Jupiter as tidally locked WRT the Sun (or somehow otherwise rotating other than the way it actually does). The goal was for Jupiter's rotation not to distract from the message, so Jupiter was not rotating at all. Riding along with Europa but with Jupiter not rotating unfortunately gave the false impression that Jupiter was rotating backwards. This graphic has now been revised showing Jupiter rotating, alleviating this problem, but rotating much slower than actual speed, as to not be overly distracting. http://photojournal.jpl.nasa.gov/catalog/PIA10149? Thanks for the feedback! |

The goal was for Jupiter's rotation not to distract from the message Probably for most people it didn't. But I'm the kind of guy who whispers to the person next to me in the movie theatre if the sun appears too high in the sky for the latitude and season that a scene is set in, or if the sun is on the left of someone who is supposedly driving east in the northern hemisphere. I'm glad that for one, my pedantry had an impact! |
